 ### Update for Edge Version 132
 
 With the release of Edge Version 132.0.2915.0, a change was introduced that affects the handling of `.crx` files (Chrome extension files). The `DownloadRestrictions` policy now blocks the download of `.crx` files if configured to block dangerous file types (options 1, 2, or 3). This change was introduced through Chromium and is documented in the Chromium code review.
